1 Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick
Start Guide.
2 Go to Maintenance > Sys OP Mode. Check your System Operation Mode setting.
• If the NBG6716 is in Router Mode, make sure the WAN port is connected to a broadband
modem or router with Internet access. Your computer and the NBG6716 should be in the same
subnet.
• If the NBG6716 is in Access Point Mode, make sure the WAN port is connected to a
broadband modem or router with Internet access and your computer is set to obtain an
dynamic IP address.
3 If the NBG6716 is in Router Mode, make sure you entered your ISP account information correctly
in the wizard or the WAN screen. These fields are case-sensitive, so make sure [Caps Lock] is not
on.
4 If you are trying to access the Internet wirelessly, make sure the wireless settings in the wireless
client are the same as the settings in the AP.
5 Disconnect all the cables from your device, and follow the directions in the Quick Start Guide again.
6 If the problem continues, contact your ISP.
I cannot access the Internet anymore. I had access to the Internet (with the NBG6716), but
my Internet connection is not available anymore.
1 Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick
Start Guide and Section 1.7 on page 18.
2 Reboot the NBG6716.
3 If the problem continues, contact your ISP.
The Internet connection is slow or intermittent.
1 There might be a lot of traffic on the network. Look at the LEDs, and check Section 1.7 on page 18.
If the NBG6716 is sending or receiving a lot of information, try closing some programs that use the
Internet, especially peer-to-peer applications.
2 Check the signal strength. If the signal strength is low, try moving the NBG6716 closer to the AP if
possible, and look around to see if there are any devices that might be interfering with the wireless
network (for example, microwaves, other wireless networks, and so on).
3 Reboot the NBG6716.
4 If the problem continues, contact the network administrator or vendor, or try one of the advanced
suggestions.
